Local delivery to an exchange store is not happening. We have one FE and two BE exchange servers all running 2K3 sp2. Last night one of the servers stopped delivering local mail. Users were also unable to access their mailbox through OWA (but could through an internal MAPI connection). There are several event log entries in the app log with ID 623 saying the version store has reached its max limit. I am running ISINTEG on the mailstore now to see if there are any issues. I have also disabled AV scans for both file and exchange scanning on the server. PLEASE HELP!!!!
